FROG-POINT.

` QPECIFICATION forming part of Letters Patent No. 788,456, dated April25, 1905.

Application filed May 21,1904. Serial No. 209,020.

To @ZZ w/wm it may concern:

Be it known that I, THOMAS DoNoIIoE, a citizen of the United States,residing at Carnegie, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in Frog-Points,of which improvement the following is a speciication.

This invention relates to an improved frogpoint for railway-tracks, andis particularly adapted for use in coal-mines and such like narrow-gagetramways; and it consists in the certain details of construction andcombination ofparts, as will be fully described hereinafter.

In the accompanying drawings, Figure 1 is a plan view of my improvedfrog-point, showing the rails connected thereto, the same beingconstructed and arranged in accordance with my invention. Fig. 2 is aside elevation of the frog-point. Fig. 3 is an end sectional elevationof the same7 the said section being taken on the line X X of Fig. 1.

To put my invention into practice, I form from cast metal a body portion1, triangular in shape, the top surface of which is used as the treadfor the wheels of the cars passing over the same, and the said bodyportion formed at the base and on two sides thereof with {iangesextending outwardly, and the said flanges 4 formed with spike openingsor slots 5, by means of which the frog-point is secured to the ties 10.Formed at the rear of this frog-point 1 are recesses 2, the contour ofwhich in vertical section is the same as that of the rails 6, forming aportion of the track. Two or more bolt openings 8 are formedtransversely through this rear portion 3 of the point,which by means ofthe bolts 9 serves to attach the said rails 6 firmly in position, as

will be seen by reference to Figs. 1 and 3 of the drawings. The railsleading to the point 1 are shown in dotted lines 11 and are similar tothose now in common use.

The advantage of a frog-point constructed as described is that it ischeap, durable, and Inay be easily detached and replaced from oneturnout to another and that the rail ends require no fitting.

Slight modifications and changes may be made in the details ofconstruction without departing from the spirit of the invention.Therefore I do not w-ish to confine myself to that shown and described.

Having thus described my invention, what `I claim, and desire to secureby Letters Patent, is-

The herein-described frog-point, consisting of the body portion 1,triangular in form, the peripheral anges 4, formed integral with thebase, the said flanges being formed with spike-openings 5, the recesses2, formed at the rear arranged at the same angle as that of the sides ofthe point 1, and the vertical contour of which is similar to that of thesides of the rails 6, the bolt-openings 8 formed transversely throughthe rear of the point, and the bolts 9 as a means of connecting therails to the same, all arranged and combined for service, substantiallyas and for the purpose described.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.

THOMAS DONOIIOE.
